I also am a huge fan of Zurb and Foundation but I'm not sure why this implementation is any better than picturefill. I still have to write a whole bunch of stuff I shouldn't have to write.
Markup for an image should not be several lines long.
I agree it shouldn't, this is why I call it a stopgap measure. Beyond the fact we both dislike extra markup I do find this solution cleaner than picturefill however, at least there are no extra divs inside the markup itself just a data attribute.
